INDICATION OF FAULT CONDITIONS
The HF2013DX-A has the following indicationson the front LCD panel:
G2 Measure of the Grid current.
HV Measure of anode voltage by LCD graph
IA Measure of anode currency by bar graph
FAULT Fault Condition – See RED flashing indicators.
OPR Amplifier in operation mode
STBY Amplifier in standby mode
WAIT Heating tube after switching on – Please wait 150sec
TEMP Measuring of the tube exhaust temperature
G1MAX Grid Current exceeded maximum
Should a fault condition appear during the tuning or operation of the amplifier the
safetycircuits of HF2013DX-A will react. The amplifier will be turned to STBY mode. After
approx. 5seconds the control circuits will switch the amplifier back to OPR . If the fault repeat 3
times, the control circuits will turn the amplifier to STBY . You must toggle the OPR/STBY
switch to reset this fault condition. After the reaction of safety circuits the FAULT LCD will be lit
up for approx. 5 to 10 secdepending on the nature of the fault.
FLASHING LCD SIGNALS:
IP anode current exceeded
HV low anode voltage
FAULT reflected output exceeded
GRID MAX first grid current exceeded
screen grid current exceeded
GRID MAX + HV maximum load power exceeded
HV + IP tuning fault, incorrect tuning of the Pi-L output circuit
In case your HF2013DX-A amplifier is not working correctly, please contactthe manufacturer
or your distributor.
